The Mesopotamian goddess of the underworld, Ereshkigal is most well known for her dealings with the goddess of heaven, and her sister, Inanna.
Your prompt is ERESHKIGAL.
Between two rivers
The Lady of the Great Earth
Rules the underworld
When Inanna came to her seeking to extend her reach into the underworld, Ereshkigal had her stripped of her clothing and power, killed, and her body hung on hooks. She eventually traded Inanna for Inanna’s husband, Dumuzid.
The jealous goddess,
Her domain a place of fear.
Tread lightly in Kur.
Perched squatting on your soul
I lean my breasts in
so you may suckle
the fresh black milk of your death
